To all whom t may concern.' s

Be it known that I, JAMES H. Bove, a citizen of the United States,residing at Chicago, in the county of Cook and rtate of Illinois, haveinvented certain new and useful Improvements in Curtain-Rods, of whichthe following is a specification.

This invention relates to curtain rods of the so-called iiat rod type atpresent eXtensively used, and has reference more particularly toeXtensible telescoping rods of this type. The leading objects of theinvention are, to provide a rod possessing a high degree of strength andrigidity against bending strains in both vertical and horizontal planes,to provide a rod the sections of which will slide easily upon each othereven though the rod sections may be slightly bent or bowed in a frontand rear direction, to provide a rod that shall be free from anydownward bending or sagging tendency under the weight of the curtain,and, generally, to provide an improved curtain rod of the type specifiedcharacterized by simplicity and economy of structure and ease ofmanipulation in mounting and adjusting the same.

In order that the invention may be clearly understood I have illustrateda preferred embodiment thereof in the accompanying drawing, in which-Figure 1 is a front elevation of the upper portion of a window casing,showing my improved curtain rod mounted thereon.

Fig. 2 is an enlarged fragmentary rear elevation of the intermediatetelescoping portions of the two rod sections; and

Fig. 3 is a further enlarged cross-section on the line 3--3 of Fig. 2.

Referring to the drawing, 5 indicates the top and 6 the side members ofan ordinary window frame or casing, on which latter are mounted brackets7 Supported by and between the brackets 7 is my improvel cur-v tain rodcomprising the telescoping rod sections designated generally by 8 and 9.The larger rod section 8 comprises the flat front wall 10, rounded upperand lower edge walls 11, and flat rear wall sections 12 having theinwardly turned oblique free margins 13; all of said parts being foldedand bent to the shape shown from a single sheet metal blank. Theinturned margins 13 do not touch each other, but form between them acentral narrow longitudinal slot 14; in the rear wall of the rod.

The smaller rod section 9 has substantially the same shape as the largersection 8, but is sufliciently smaller in transverse dimensions totelescope within the latter. It is also folded and bent to form from asingle sheet metal blank, and comprises the flat front wall 15, roundedupper and lower edge walls 16, and flat rear wall sections 17 having theinwardly turned oblique free margins 18; the free edges of the latterbeing spaced apart slightly wider than the free edges of the margins 13.It will be observed by reference to Fig. 3 that the portion of the innerrod section that lies within the outer rod section is not in surfacecontact with the latter throughout its entire eX- tent, but bearsthereon only at its frontV wall .15 and at the edges of its inwardlyturned marginal portions or flanges 18 which engage with the edges ofthe inwardly turned marginal portions or iianges 13 of the outer rodsection, the transversely acting elasticity of the two rod sectionsmaintaining the front walls 10 and 15 in contact and likewise the edgesof the iianges 13 and 18 in contact.

This affords sufficient friction between the two rod sections to preventthem from sliding apart by gravity when mounting the curtain on the rodor mounting the latter on, or dismounting it from, its supportingbrackets '7 and at the same time it renders the rod adjustable to therequired length under a light pull or push. The described constructionalso prevents sagging, since the elastic pressure contact of the edgesoi the flanges 13 and 18 is continuous throughout the telescopedportions of said rod sections and one component of this pressure acts ina vertical direction to oppose relative movement or yield of the rodsections in such vertical direction. Furthermore, the two sections willreadily telescope, even though either or both of them be slightly bentor bowed in a front and rear direction, owing to the elasticity of therear wall sections 12 and 17 which are free to yield outwardly underpressure ot the flanges 18 of the inner rod section on the flanges 13 ofthe outer rod section. Again, the inturned margins or fianges 13 and 18directions of both its vertical and horizontal transverse axes,affording an even stronger greatly stiien and strengthen the rod in thef resistance to bending strains than is obtained by extending the rearwall sections toward each other until their free edges meet.

I claim- 1. A hollow flat curtain rod, Comprising telescoping rodsections each having a solid fiat front wall and a longitudinallyslotted flat rear wall, the marginal portions of said flat rear wall oneither side of the slot of the latter extending inwardly toward the'front wall continuously throughout the full length of each rod section.

2. A hollow dat curtain rod, Comprising telesooping rod sections eachhaving a solid flat front wall, rounded edge walls, and a longitudinallyslotted flat rear wall lying substantially parallel with said frontwall, the marginal portions of said flat rear wall on either side of theslot or" the latter extending inwardly toward the front wallcontinuously throughout the full length of eaeh rod section.

3. A hollow flat curtain rod, comprising telescoping rod sections eachhaving a solid flat front wall, rounded edge walls, and a longitudinallyslotted flat rear wall lying substantially parallel with said irontwall, the marginal portions of said fiat rear wall on either side of theslot of the latter extending inwardly toward the front wall; theteleseoping portions of said rod sections lying in Contact with eachother substantially only at their front walls and the inwardly extendedmarginal portions of their rear walls.

4. A hollow flat Curtain rod, comprising telesooping rod sections eachhaving a solid i'lat front wall, rounded edge walls, and a centrallylongitudinally slotted flat rear wall lying substantially parallel withsaid front wall, the marginal portions of said flat rear wall on eitherside of the slot of the latter extending obliquely inwardly toward thefront wall; the telesooping portions of said rod sections hearing uponeach other substantially only at their front walls and at the free edgesof the inwardly extended marginal portions of their rear walls.
